Engine Specification

About the BMW B58B30C Engine

The BMW B58B30C is the PHEV-specific variant of BMW’s acclaimed B58 3.0-litre turbocharged inline-six engine — one of the most highly regarded six-cylinder petrol engines in the current automotive market. The B58 family replaced the previous N55 engine and has been universally praised for its combination of power output, refinement, reliability, and tuning potential, receiving recognition as an International Engine of the Year award winner and earning a strong reputation among both road drivers and performance builders.

The B58B30C designation identifies the specific variant of the B58 calibrated for the X5 xDrive45e plug-in hybrid application, where the combustion engine works in conjunction with a rear-mounted electric motor to deliver a combined system output. In combustion-only specification, the B58B30C produces 290 kW (394 hp) — a figure that reflects the engine’s inherent performance capability without electric assistance.

The B58’s architecture includes a twin-scroll turbocharger, direct and port injection (combined VALVETRONIC / Valvetronic injection), Double VANOS variable camshaft timing, Valvetronic variable valve lift, and a closed-deck aluminium block — a specification that reflects BMW’s investment in this engine family across their widest range of applications, from the M240i and 540i through to the M-tuned M40i and M variants.

iPerformance PHEV Application – What Buyers Should Know

The B58B30C is the plug-in hybrid variant of the B58, specifically calibrated and configured for use alongside the X5 45e’s electric drivetrain. While the engine shares its fundamental architecture with other B58 variants, buyers should confirm compatibility between this unit and their specific X5 45e variant before purchase — including the vehicle’s build year, hybrid system generation, and xDrive configuration.

The engine is supplied with all combustion engine attachments as shown in the photographs. The electric motor, high-voltage battery, and associated PHEV components are separate drivetrain elements not included with this engine sale. Please contact us to confirm the exact specification of this unit and its compatibility with your vehicle.
